Every year, at the end of October, tens of thousands of people flock to a Buddhist temple in China to see a huge gingko biloba tree (银杏树) drop its foliage (枝叶) and turn     1     temple from green to gold.

The Gu Guanyin Buddhist temple, located in the Zhongnan Mountains of China’s Shaanxi Province is home     2    a 1,400-year-old gingko biloba tree.

It towers superbly over the temple,    3    for a few days every autumn, it rains down a gold carpet of leaves that stands out against the muted tones of the season.

Inspired by the Belt and Road Forum for International Cooperation held in Beijing, Cao decided to cover the route by hiking as a tribute (致敬) to the ancient Silk Road.     1     friend of his, Wu Fan, volunteered to be his companion during the trip.

Now, Cao has started the second part of his dream to walk along the Belt and Road route. He flew 4, 700 kilometers     2     Xi’an to Kashgar on Sept. 20, planning to hike back to Xi’an in five months.

3 . As data and identity theft becomes more and more common, the market is growing for biometric(生物测量) technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.

Researchers from Georgia Tech say that they have come up with a low-cost device(装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to—regardless of whether someone gets the password right.

It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.

In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.

4 . Today’s world is not an easy adjustment for young adults. A key skill set for success is persistence (毅力), a characteristic that researchers say is heavily influenced by fathers. Researchers from Brigham Young University discovered that fathers are in a unique position to help their adolescent children learn persistence.

BYU professors Laura Padilla-Walker and Randal Day arrived at these findings after following 325 American families over several years. And over time, the persistence gained through fathers led to higher achievement in school.

“There are relatively few studies that stress the unique role of fathers,” Padilla-Walker said. “This research also helps to prove that characteristics such as persistence — which can be taught — are key to a child’s life success.”

Researchers determined that dads need to practice an “authoritative” parenting style. Authoritative parenting is not authoritarian: rigid, demanding or controlling. Rather, an authoritative parenting style includes some of the following characteristics: children feel warmth and love from their father; responsibility and the reasons behind rules are stressed; children are given an appropriate level of autonomy (自主权).

In the study, about 52 percent of the dads exhibited above-average levels of authoritative parenting. A key finding is that over time, children raised by an authoritative father were significantly more likely to develop persistence, which leads to better outcomes in school.

This particular study examined 11 to 14-year-olds living in two-parent homes. Yet the researchers suggest that single parents still may play a role in teaching the benefits of persistence, which is an avenue of future research.
